The effect of a high unsaturated-low saturated fat diet on serum cholesterol levels were studied. Subjects were clinic patients receiving the following hypocholesterolmeic agents: triparanol (MER-29), diildothyroacetic acid (Diac), dextrothyroxine (d-T₄) and 3-methoxy-16, alpha-methyl-1,3,5, (10)-estratriene-16 beta, 17 beta-diol (Manvene or Anvene).

Fifteen hypercholesterolemic patients, eleven of whom were diabetic, were placed on diets with prescribed amounts of unsaturated fat. The caloric distribution was 40 per cent carbohydrate, 20 per cent protein, and 40 per cent fat. The level of unsaturated fat was 70 per cent of the total fat.

Seventy-one per cent of the patients on the hypocholesterolemic …

A Review Of Drug Addiction And A Study Of Its Relation To Carbohydrate Metabolism, Eppie Chung Hartsuiker

Loma Linda University Electronic Theses, Dissertations & Projects

The specter of addiction eventually involves everyone of the community. It is a three-fold problem of socio-economic, psychological, and physiological factors. The least understood is the physiological or biochemical aspect of addiction.

It has been postulated that an upset in carbohydrate metabolism may be a biochemical cause of addiction. Several avenues were employed to investigate this possible cause of addiction.

1. A diet survey was conducted and revealed a greater consumption of refined carbohydrates, confections and alcoholic beverages in addicts.

2. Five-hour oral glucose tolerance tests were performed on 7 addicts and 12 non-addicts. These tests revealed that there were decreased glucose …

Application Of Knowledge Of Medications By Senior Students In A Selected School Of Nursing, Patricia H. Okimi

Loma Linda University Electronic Theses, Dissertations & Projects

The problem arose from the need to study the present method of pharmacology instruction in a selected school of nursing. "How much knowledge of medications do selected senior students have, and how do they apply their knowledge in the administration of medications?"

For this study, the normative survey approach was used as the method of research. Eleven senior students of nursing engaged in the administration of medications, as team leaders, were observed and questioned on two different occasions during one quarter of their school year. The tool of research used to collect data was an observation code sheet developed for …

The Effect Of The Shave On Infection In Maternity Patients, Doris Christine Bethea

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to find out if the shave routinely received by maternity patients could be limited to the perineal area without increasing the incidence of infection among these patients. The experimental method, with the parallel group technique and a single variable, was used.

The study was conducted at two hospitals; the White Memorial Hospital in Los Angeles, California, called Hospital A; and the Washington Sanitarium and Hospital in Takoma Park, Maryland, referred to as Hospital B. Data were collected on ninety clinic patients at Hospital A and on two-hundred and one private patients at Hospital B. …

A Study Of The Bacteriological Effectiveness Of Oral Thermometer Procedures In Three Selected Hospitals, Esther Mae Rose

Loma Linda University Electronic Theses, Dissertations & Projects

Because pathogens such as streptococcus and staphylococcus have been transferred in many hospitals, the source of the infections is of concern to doctors, nurses, and other medical personnel. As shown by the review of literature, good techniques are necessary to stop the spread of disease.

It was the purpose of this study to investigate one facet of patient safety by: (1) the culture of thermometers ready for use in three selected hospitals; (2) to determine the effectiveness of the Group, Individual, and Central Supply methods of disinfection currently practiced in the three selected hospitals.

The method for the experiment of …

Pharmacological Studies Of Antidiabetic Chinese Herbs, Mun Fa Lee

Loma Linda University Electronic Theses, Dissertations & Projects

Rehmannia glutinosa, Atractylus ovata, and Polygonatum chinense have all been employed by the Chinese as oral antidiabetic agents and reported by Min (1928), Kin (1931), and Li et al. (1936) to possess hypoglycemic activity. This prompted the pharmacological studies of these herbs.

Materials and methods. Their pharmacognosy was condensed from all available Chinese and scientific literature. Preliminary chemical and physical analyses included determinations for moisture, ash, crude fat, carbohydrates, protein, phosphorus, pH, alkaloids, melting point, and spectroscopy.

Natural History Of Thelazia Californiensis Price, 1930 (Nematoda: Thelaziidae), A Mammalian Eye Worm, Warren E. Parmelee

Loma Linda University Electronic Theses, Dissertations & Projects

Various factors—embryology, host associations, and seasonal changes In eye worn populations—tending to promote the propagation of T. califomlensls were studied.

The early embryology closely parallels that of other nematode species.

The mature embryos remain alive in saline at 35°C as long as 5 days. Dead embryos can be distinguished from living ones by virtue of the rapid staining by methylene blue by the former. Parturient female thelazias release embryos into saline, and embryos are found regularly in tear secretions of infected laboratory rabbits.

Ovic embryos possess an enveloping egg membrane containing chitin. On this account, this eye worm species is …

The Effect Of Preweanling Administration Of Carbohydrates Used In Infant Formulas On Subsequent Dental Caries In White Rats, Erlinda Amor Romulo

Loma Linda University Electronic Theses, Dissertations & Projects

The high incidence of tooth decay, one of the most common diseases found in all age groups, gives a reason for the study of methods to prevent dental caries. Certain dietary factors, specifically carbohydrates, have been implicated in the decay process. Since diet influences both the oral and systemic environments in which the teeth develop, mature, age, and decay (1), many studies have been conducted to determine the effects of oral administration of different carbohydrates on dental caries. The extrinsic effects of diet on the mature erupted tooth have, however, been the major concern of the research (2).

The first …

Natural And Experimental Infections Of Thelazia Californiensis Price (1930, Nematoda: Thelaziidae) With Descriptions Of The Adult And Larval Parasites, Howard S. Burnett

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this work was to determine the extent and effects of infestation of the eye worm of mammals, Thelazia californiensis, and to elucidate through experimentation or observation the mode of transmission.

A survey of literature revealed that thelaziasie (infestation by Thelazia species) may cause serious pathological changes in the eye and its adnexa, sometimes resulting in blindness. It was found that reports of thelaziasis in the United States were (with two exceptions) of cases in California. It was further found that T. californiensis has been reported in a wider variety of host than has any of other …

Some Supplementary Studies With Wheat Proteins, Gerald G. Porter

Loma Linda University Electronic Theses, Dissertations & Projects

[Abstract Not Included]

Introduction The importance of selecting only foods containing proteins of high nutritive value has been somewhat over-emphasized in the past because of the failure to recognize the possibility of supplementary relationships among proteins that are not of high quality. Hart (11) has wisely suggested that a food should not be relegated to an inferior class because its proteins, when fed alone, are not of high biological value. Sherman (31) has reminded us that with a knowledge of the nutritional chemistry of the proteins of various foods, it becomes relatively easy to utilize their supplementary relationships so that …
